When making up (i.e. connecting) or breaking out (i.e. disconnecting) drill pipe, casing, tubing, or other pipe, tongs are used. Manual tongs, which are effectively large wrenches, are known for manually turning the pipe during make up or break out of pipe. Power tongs or power wrenches are also known that are pneumatically or hydraulically operated tools that operate to rotate the pipe during make up or break out.
